My dog just finished heat. Why is there stringy mucus when she pees?

It's possible that the discoloration is from the tail-end of Ripley's heat cycle, however, if the spots continue for more than a day or so, or you begin to see other issues such as more frequent urination, cloudy urine, straining to go (squatting a lot with small amounts, etc), or other more systemic symptoms such as vomiting, diarrhea, changes in appetite, etc, it's a good idea to get Ripley into your vet to rule out any other issues such as a urinary tract infection.

She should not be back in heat this quickly. Did the vet run a urine test to check for a UTI? Have they prescribed any medications? That is where I would start. I suspect it is normal post-partum discharge she is having but it is best to have her checked out. I strongly recommend having her spayed as soon as possible.

Thanks for using Petco Pet Education Center, formerly Petcoach. If there are no other signs of heat (swollen vulva, swollen teats), then I am concerned for a urinary tract infection. Take Molly and a sample of her urine in to the vet. If there ARE signs that she is in heat, talk to your vet about testing for an ovarian remnant (a few ovary cells left in the body can be enough to trigger a heat sometimes). Best wishes to you and Molly!

When you say you saw a white discharge you do not indicate where you saw the discharge coming from. Since you discussed heat later in the question I assume you mean you saw discharge from the vulva. An occurrence small amount of whitish discharge can be a normal finding. However, if you are noticing a yellow or blood tinged discharge, if she is drinking more than usual, if she isn’t eating well or otherwise acting “sick” then I would be concerned. Pyometra is an infection of the uterus and can be fatal. So if you are concerned that you are seeing abnormal vaginal discharge then she should be seen by a veterinarian as soon as possible. If this is the problem they will recommend to have her spayed immediately . Best of luck and I hope she is back to normal soon. Thank you for using Pet Coach.

Mucous could be a sign of a urinary tract infection if accompanied by frequent urination or blood in the urine. It can also be seen with vaginitis. A small amount of mucous can be normal for some dogs. If you're only seeing mucous and Zelda is not excessively licking her vulva you can probably monitor for a few days but if the mucous continues I'd recommend having your vet examine her.

The appearance of Roxie's urine could be caused by a urinary tract infection, crystals in the urine, or a growth or stones in the urinary tract. It is important that you make an appointment to have Roxie seen by your veterinarian as soon as you can to help determine the cause and to start treatment. If you notice her straining to urinate/unable to produce urine, this is a medical emergency and she should be seen by a vet immediately.

It sounds like Margo may have an infection in the uterus or lower genital tract. This is most common following a recent heat cycle. I would advise that she be examined by her veterinarian to confirm this. If she does have a uterine infection, your vet can advise you about the best treatment which may include oral antibiotics or having her spayed depending on the severity.
